Hello people! Here I show the schematic and the printed circuit board design of my flyback driver. I'm working on DIY content on my website and I'll keep you posted on everything.

Easy-Flyback Driver (revB 07/2021)

Thanks! I have a JF0501-1948 that I took from out of the back of a TV

It can be. I just had some 21835 laying around

Does the flyback have to be the JF0501-21835? or can it be other JF0501 transformers? I am having a hard time finding the JF0501-21835 or a datasheet on it. Thanks

amazon is where i got mine https://www.amazon.com/Pack-LM311N-Integrated-Circuits-Comparator/dp/B0BLZWYB97/ref=sr_1_1?crid=2JUDMBF7MQN5S&keywords=lm311n&qid=1669167840&sprefix=lm311n%2Caps%2C579&sr=8-1

Does anybody have an alternative to the LM311N? They appear to be on backorder till next year.
